This bill mandates that "covered materials," specifically cement, concrete, or steel, used in certain state-funded projects, referred to as "covered projects," must be produced in the United States. A state agency is prohibited from procuring these materials unless they meet this requirement, with the stipulation that materials can still be considered U.S.-produced if less than 5% of their total cost comes from components not produced in the U.S. The bill also outlines conditions under which state agencies can grant waivers to this requirement, including the unavailability of compliant materials, excessive cost increases, or emergencies necessitating immediate procurement.

Additionally, the bill requires state agencies to publish any granted waivers on their websites within 30 days and mandates the Department of Technology, Management, and Budget to provide guidance to procurement officials. It also includes a provision for a bid preference for projects that commit to using products manufactured in Michigan. The act will take effect on January 1, 2030, and will apply to procurement processes unless conflicting laws are in place.
